Ability To Add Full YuGiOh Set Like Lego

Just like Lego where it will show the pricing for the instruction manual and empty box separately and then the full set, we should be able to list full TCG sets like the collectible Yu-Gi-Oh tins for example instead of only the cards in them separately.

This way we would be able to see and track the pricing for the tins even empty and full.

Right now the only way to add TCG cards is individually, so even if I wanted to add these sets I couldn't as a contributor.

Please add the ability to add sets along with the feature you already have to add single cards, thank you.
